SCALE.

Application filed November 5, 1915.

To all whom it may concern:

Be it known that we, AXEL SAMUEL Voc'r, a subject of the King of Sweden,and Crrannns E. BARBA, a citizen of the United States, both residing atAltoona, in the county of Blair and State of Pennsylvania, have inventedcertain new and useful Improvements in Scales, of which the following isa specification.

This invention relates to scales, and particularly to those using a loopfor transmitting proportionate loads from one scale beam to another bymeans of engaging pivots, and to this end this invention contemplates animproved loop having a plurality of pendent perforated legs, suitablysecured to a cross beam so designed as to present an ample bearing faceto the support which carries the same.

The primary object of this invention is to construct a loop of aplurality of parts which not only greatly facilitates the removal ofbeams, when such is necessary, but provides a very practical Way ofrenewing the pivots when the same are affected.

Another object of this invention is to provide positive means of aliningthe pendent legs of the loop, so as to insure greater freedom of thebearing pivots as well as accuracy of the scales.

Another object of the invention is to provide means whereby the variousstresses to which the loops are subjected are reduced to such that areeasily calculated as simple tension and bending stresses.

A still further object of the invention is to provide a scale loop thatis susceptible of being hardened sufficiently to resist the wear of thepivot points, thus obviating the 1 necessity of inserting in the eye ofthe loop,

a section of material for this purpose, which not only is difficult tomaintain, but gives rise to inaccurate alinement of the pivot axis andhence an inaccurate scale.

lVith these and other objects in view, which will become more readilyapparent as the nature of the invention is better understood, the sameconsists of the novel construction, combination and arrangement of partsas will hereinafter be fully pointed out, illustrated and claimed.

It will be quite readily understood that this invention is susceptibleof some structural change and modification without departing from thespirit or scope of the invention, but a preferred and practical formSpecification of Letters Patent.

of the invention is shown in the accompanying drawings, in which;

Figure 1 is a front elevation of the improved loop, showing the mannerof attaching the pendent legs to the transverse beam or top member.

Fig. 2 is a side elevation of the parts shown in Fig. 1.

Fig. 3 is a side elevational view of the top beam member, showing indetail the alinement recesses which are engaged by a cooperating ledgeon the pendent element.

Fig. at is an inverted plan view of the parts shown in Fig. 3.

Fig. 5 is a cross section taken on the line 6-6 of Fig. 2.

Fig. 6 is a cross section taken on the line 5-5 of Fig. 3.

Fig. 7 is a top plan view of one of the 7 pendent legs with the beamremoved.

Like reference numerals refer to corresponding parts throughout theseveral figures of the drawings.

In carrying out this invention no change is contemplated in the usualform or construction of the scale beam or scale mechanism proper, and tothis end we have constructed a beam loop designated in its entirety bythe numeral 10, such that the same can readily be placed on a pair ofscales equipped with the usual integral loop, after the removal of thesame.

The loop 10 is constructed in three parts, viz; the pendent arms or legs11 and the beam or yoke piece 12. The pendent arms 11 have the usualform of eye 13, with the knife edge engaging portion 1 1 being slightlyextended on, either side, as at 15 in order to provide additionalbearing surface.

The shank 16 of the pendent legs is preferably made with a taper whichmerges into a shouldered portion 17, as shown clearly in Fig. 1 of thedrawings.

The shouldered portion 17 is provided with an upstanding alinement ledge18 which engages a cooperating recess 19 in the beam member 12. Thependent arms 11 are further provided with an extended cylindricalsection 20, adapted to fit snugly in the opening 21 of the beam 12. Theupper edge of the section is threaded and is also provided with someform of lock washer 22 and nut 23, for drawing the parts together. Thebeam 12 is preferably made with a slight shoulder or boss 24 adjacent tothe lock washer 22, for the purpose of facing the same in order tofacilitate fitting. The central portion of the beam 12 is preferablyprovided with a semi-cylindrical section, as shown in Fig. 6 of thedrawings, this form of section being admirably adapted for the purposeintended and conforms to the section found in the usual integral loops.The pendent legs, as well as the beam members, are preferably made ofchrome bearing steel in suitably constructed dies.

Having thus described our invention it is thought that the manyadvantages will be readily understood without further elaboration, andwhat we claim and desire to be secured by Letters Patent, is 1- 1. Aloop for scales comprising a beam member having openings at each endthereof, and recessed on one face adjacent each opening, pendent legmembers having an eye at their lower ends, and formed at their upperends to fit in said openings, said leg members also having a shoulder atthe junction of the portion thereof which fits in the beam openings withthe body for interlocking with said recess and means for engaging theends of said leg members projecting through the openings to clamp thesame in position.

2. A loop for scale beams comprising a yoke piece having recesses, aplurality of parallel legs carried by said yoke piece and each having aneye at its lower end and a shoulder at its upper end, and an upstandingoblong ledge on said shoulder portion for interlocking with one of therecesses of the yoke piece, and means for holding the leg members to theyoke piece whereby the eyes of the leg members are maintained atright-angles to the long side thereof.

In testimony whereof we affix our signatures in presence of twowitnesses. AXEL S. VOGT. CHARLES E. BARBA. lVitnesses:
